Celestial Events

The Planets this Week

  • Mercury is currently too close to the sun and is not visible. The tiny planet passes behind the sun (superior conjunction) on May 27.
  • Venus is the brilliant Evening Star, easily seen above the western horizon right after sunset. The gap between the planet and the sun is diminishing day by day: Venus now stands about 15 degrees high at sundown, and appears lower each evening. Venus remains visible for about two hours after sunset. The thin crescent moon will be near Venus on the evening of May 22. The planet is en-route for its historical crossing in front of the sun (“transit”) on June 5.
  • Mars appears at dusk above the southwest horizon, and sets in the west around 2 a.m. The Red Planet is still fading and is now only about as bright as some of the brightest stars. The first quarter moon passes below Mars on the evening of May 28.
  • Jupiter passed behind the sun (conjunction) on May 13 and is not currently visible. The giant planet will reappear in the dawn sky in June.
  • Saturn appears above the south-southeast horizon at dusk, culminates in the south around 10 p.m., and sets in the west-southwest at the crack of dawn. The ringed planet is currently near bright star Spica, in the constellation Virgo: the waxing gibbous moon joins this celestial pair on the night of May 31 to June 1.
